W'ILLIAM SHAW, OF PARIS, KENTUCKY.

GRAIN-CLEANING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 272,782, dated February20, 1883.

Application filed November 6, 1882. (No model.)

To all whom it may concern Be it known that I, WILLIAM SHAW, a citizenof the United States of America, residing at Paris, in the county ofBourbon and State of Kentucky, have invented certain new and usefulImprovementsin Grain-Cleaning Apparatus; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which form a partof this specification.

My invention relates to certain new and useful improvements in means forcleaning grain and separating the impurities therefrom by permitting thegrain to descend through a pipe or flue upon the periphery of a wheelprovided with wings or buckets, which wheel is provided with a shaft andpulley, and is connected by suitable mechanical means with a suction-fanlocated in a spout which adjoins the grain-flue for the purpose ofcreating a draft which will carry oh" the refuse or impurities from thegrain and force them outside of the building.

My invention consists in a ware or store house or granary having avertical opening or flue, which is connected with the separate stories,and in locating within said line a wheel upon the periphery of which thegrain falls, said vertical line being provided with an opening or linewhich is connected with a suction-fan.

My invention also consists in the construction and combination of theparts, as will be hereinafter described and claimed.

In the annexed drawings, Figure 1 is a perspective View of mygrain-cleaning apparatus, showing the parts disconnected or removed fromthe building. Fig. 2 is a sectional view of a warehouse or granary,showing my invention applied thereto.

In the annexed drawings, A represents a vertical line or opening, whichmay extend from the upper story of a building to the ground-floor. Thefloors of this building adjacent to the flue are provided with raisedportions a, which will afford an-easy means for feeding the grain to theaforesaid flue; or the floors may be built so as toincline toward thisflue. The grain, when it descends, falls upon the periphery of the wheelB, so as to cause it, by the force of gravity which is utilized, toclean the grain, which cleaning is accomplished by a suction-fan, G,which is connected to the wheel .B by suitable mechanical means, asimple way being by a belt, as showna The flue A, below the fan, isconnected with the flue D, which is at right angles with the same.Adjacent to and parallel with thisflue D is another flue, E, which isseparated from the aforesaid flue by a partition, the inner wall ofwhich is perforated or otherwise connected with the horizontal flue D.Within this flue E is located the suction-fan. By these means the grain,as it descends, causes the driving wheel or pulley on the wheel B torotate, which pulley is connected by means of a belt, as.

shown in Fig. 2, to the fan 0 for the purpose of creating a draft, whichwill draw the impurities from the grain and discharge them at the end ofthe line E.

In the annexed drawings I have shown one way of carrying out myinvention, though it is evident that as to the mechanical details 'theymay be varied according to the locality and the arrangement of the linesin the building in which it is desired to use the invention, the mainobject of my invention being to utilize the power which can be gained bythe descent of the grain to operate suitable mechanism to produce asuction which will draw and discharge the lighter impurities from thegrain in its descent.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent, is

1. In a building or warehouse, the combination, with a vertical and ahorizontal line, of a wheel located within the vertical fine and adraft-fan located in the horizontal flue, substantially as shown, andfor the purpose set forth.

2. In a grain-cleaning apparatus, the combination, with a vertical lineor chute, A,having openings for the supply of grain, as shown, of thewheel B, having its periphery in said chute, flues D and E, andsuction-fan O, the parts being organized substantially as shown, and forthe purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM SHAW.
